Using ultrasound imaging to diagnose heart attacks without ST elevation

This trial is testing whether a special type of heart ultrasound with contrast dye (called Sonovue) can help doctors diagnose heart attacks more accurately when patients arrive at the hospital with symptoms. Right now, doctors often have to do an invasive procedure (threading a tube into the heart arteries) to confirm whether someone has had a heart attack. The researchers want to see if this safer ultrasound imaging can help avoid unnecessary invasive procedures by distinguishing a real heart attack from other conditions that look similar.

Many patients who come to the hospital with chest pain have unclear symptoms, and doctors can't always tell right away if they've had a heart attack. This sometimes leads to unnecessary invasive heart procedures that carry their own risks. This study aims to find a safer, non-invasive way to quickly and accurately diagnose heart attacks using improved ultrasound imaging.
